A
Actionable

When information about a person’s genes is described as “actionable”, it means that we know enough about the genetic result to make a health decision or action.

Afib

Afib is short for Atrial Fibrillation. It happens when the heart beats out of rhythm. Afib affects the top chambers of the heart (called the atria). Afib is studied in adults in eMERGE 4.

Allele

A person typically has two versions of a gene. Each version is called an allele. For the majority of genes, one allele version is inherited from a person’s mother and one from their father. Sometimes one allele version may increase risk of disease, while another may not. Other times both alleles are identical. If the alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous for that gene.

Asthma

Asthma is a common lung disease. Asthma symptoms such as wheezing, cough, shortness of breath, fast breathing, or tightness in the chest are due to narrowing of the airway tubes. Asthma is a lifelong disease that can be controlled. Asthma is studied in children in eMERGE 4.

Atrial fibrillation

Atrial fibrillation, or Afib happens when the heart beats out of rhythm. Afib affects the top chambers of the heart (called the atria). Afib is studied in adults in eMERGE 4.
